Welcome to Hell, cruichin ... I mean, to the wonderful world of photoetch radar screens. My personal bugaboo is the SPS-49 found on modern US Navy ships, with the nastly little curve of the main screen and the tricky bending and gluing of the back brace. And then the bazillion times I manage to knock it apart while doing something else ...
That said, I think PE radar antennas are one of the things that really sets a model apart, and makes it look more like a miniature version of the real thing as opposed to a pool toy.
And yes, acetone is one of my best friends now as well!
